Add read barrier support to the entrypoints.
Also remove "THIS_LOAD_REQUIRES_READ_BARRIER" since reading
an ArtMethod* no longer needs read barrier.
stub_test should also work with read barriers now.

ART: Remove some of the Mac craziness
We rely on new-enough Clang/LLVM builds nowadays. The integrated
assembler supports named parameters. Throw away most of the
old duplication (effectively cutting support for older Clang
versions). The only required duplications are:
1) Clang as does not support .altmacro. However, the Clang
preprocessor works different wrt/ the GCC preprocessor
and does not give us trouble with inserted spaces.
2) On the Mac, symbols are prefixed with an underscore.
This should help to avoid breaking the Mac build when changing
the assembly code, and prepare for a complete Clang-only build
for x86 and x86-64. Switching to the integrated assembler for
the host build may be done in a follow-up CL.

Make ART compile with GCC -O0 again.
Tidy up InstructionSetFeatures so that it has a type hierarchy dependent on
architecture.
Add to instruction_set_test to warn when InstructionSetFeatures don't agree
with ones from system properties, AT_HWCAP and /proc/cpuinfo.
Clean-up class linker entry point logic to not return entry points but to
test whether the passed code is the particular entrypoint. This works around
image trampolines that replicate entrypoints.

ART: Set default visibility to protected
Set default visibility of symbols to protected. This allows the
linker to optimize internal calls and helps avoid plt calls.
Make almost all assembly stubs hidden, as -fvisibility does not
seem to apply to them. Change the assembly tests accordingly. Also
allows to clean up previous hacks to avoid plt calls.

Implement art_quick_aput_object stubs for X86-64 and ARM64
Implement the aput_object stubs for 64b architectures and enable
their testing in stub_test.
Fix missing @PLT for x86.
Add automatic _local labels in function definitions in x86-64 so we
can make local jumps (instead of PLT hoops).

Add "arch_test" gtest for assembly stub constants, add some ARM64 assembly code
Add a test that (1) checks all callee-save method frame sizes for
all architectures, (2) checks thread offsets for the runtime
architecture and (3) checks callee-save method offsets for the
runtime architecture.
The "asm_support_XXX.h" files now only contain definitions that are
common between all architectures. Architecture-specific definitions
(i.e., special registers names) have been pushed into the corresponding
.S file. This change was required to be able to undefine definitions
in the test, so that multiple tests can be written in one file.
Test (1) above is in a sense two-stage. The arch_test gtest compares
constants (if it finds them) against the frame size as reported by
the ArtMethods created by the Runtime. This works for all architectures
as we can provide the instruction-set to CreateCalleeSaveMethod. The
second stage of the "test" are preprocessor tests with "#error" in the
case that the constants are not the expected value.
Optimally I'd like to change that to an actual runtime test exercising
the assembly code, which would also allow to check whether the right
registers are stored.
Also added missing assembly code for ARM64 for the callee-save macros.
Also fix X86_64 compilation for Clang 3.5.

x86_64: JNI compiler
Passed all tests from jni_compiler_test and art/test on host with jni_copiler.
Incoming argument spill is enabled, entry_spills refactored. Now each entry spill
contains data type size (4 or 8) and offset which should be used for spill.
Assembler REX support implemented in opcodes used in JNI compiler.
Please note, JNI compiler is not enabled by default yet (see compiler_driver.cc:1875).

Always reset CFI state.
.cfi_startproc simple may do even less than .cfi_startproc, so don't rely on
it. Instead, use regular .cfi_startporc and always set up the expected entry
state.

Ensure functions start with clean CFA state.
.cfi_startproc doesn't reset CFA state and so delivering exceptions and the
like can leave the CFA with an incorrect offset. Reset the state in the
DEFINE_FUNCTION macro.
Also fix using test/run-test with --gdb for the target.

Object model changes to support 64bit.
Modify mirror objects so that references between them use an ObjectReference
value type rather than an Object* so that functionality to compress larger
references can be captured in the ObjectRefererence implementation.
ObjectReferences are 32bit and all other aspects of object layout remain as
they are currently.
Expand fields in objects holding pointers so they can hold 64bit pointers. Its
expected the size of these will come down by improving where we hold compiler
meta-data.
Stub out x86_64 architecture specific runtime implementation.
Modify OutputStream so that reads and writes are of unsigned quantities.
Make the use of portable or quick code more explicit.
Templatize AtomicInteger to support more than just int32_t as a type.
Add missing, and fix issues relating to, missing annotalysis information on the
mutator lock.
Refactor and share implementations for array copy between System and uses
elsewhere in the runtime.
Fix numerous 64bit build issues.
